This is the 3d printed wrap around glare shield for the Cessna 172 instrument panel. Created in 4 parts which slot together to form the whole assembly. These parts are then held in position with various dome head screws. The whole unit then slides onto the edge of the instrument panel and is secured with screws.
You will need a print bed size of 300mm x 300mm.
